Madonna revealed she once shared a passionate kiss with Michael Jackson as she joined James Corden on Carpool Karaoke.
The music superstar sang along to some of her biggest hits including Vogue, Papa Don't Preach and Express Yourself, before twerking to her more recent single, Bitch I'm Madonna, during the Late, Late Show sketch.
During one discussion, presenter James asked Madonna to describe a night out with Thriller singer Michael.
"You want me to kiss and tell then don't you?", she said.
James asked: "Did you kiss?
Madonna replied: "Of course. I mean baby I've been around."
When James asked Madonna if her smooch with Michael was "full French kissing," she responded: "Yeah, tongue in mouth kissing. I've never had a chance to talk about it, no one ever asks me."
Madonna said she initiated the kiss because Michael was shy.
"However he was a willing accomplice," she said. "I did get him to loosen up with a glass of Chardonnay and it did wonders."
In another revealing chat, Madonna, 58, said she once wanted to be a nun when she was younger.
"I like their uniform, it's kind of perverse," she said.
"I imagine all sorts of things are going on under that big long robe."
The Carpool Karaoke segment ended with Madonna's number one hit Music, when she decided to hang her leg out of the car window as they drove around New York.
